Available in PDF, EPUB and Kindle. Book excerpt: In Chapter1 of this timely book, radiation damage in vanadium, niobium, molybdenum and tungsten is discussed at the atomic level; treating for instance - third-stage recovery in terms of self-interstitials being mobile traps for - predominantly - vacancies. Higher recovery stages are treated by using various techniques, such as: electrical resistivity, electron microscopy, positron annihilation spectroscopy and computer simulation - thus revealing vacancy-cluster break-up in stage-V and interstitial cluster annealing in stage-VI.

This book was released on 1985 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of progress made during the first year of a three year program on the investigation of swelling mechanisms in refractory metals irradiated at elevated temperatures, i.e. 0.3 T sub m - 0.6 T sub m (where T sub m = melting point in K). The objective of this work is to achieve an understanding of the elevated temperature swelling in these body centered cubic (bcc) metals by a close coupling of theoretical development and experimental verification. Originator supplied keywords include: Swelling, Radiation effects, Ion bombardment, Refractory metals, Theory of swelling, Ion-simulation irradiation.
Download or read book Defects and Radiation Damage in Metals written by M. W. Thompson and published by Cambridge University Press. This book was released on 1974-09-12 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of radiation damage in solids generally has been stimulated by the technological demands of nuclear energy and space research. Professor Thompson's 1969 book discusses the basic atomic mechanisms which give rise to the main effects induced by radiation in metals, since it is in their relatively simple structures that the fundamental processes can be most easily identified. The first part of the book describes the nature of lattice defects in metal crystals. The presentation leads naturally into the discussion of radiation damage in the second part and recognises the important contribution that the study of irradiated metals has made to our general knowledge of defects. The wide coverage of this book includes developments in our understanding of collision cascades, of the clustering of point defects and the behaviour of impurities induced by irradiation.

This book was released on 1964 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on the effects of heat-treating and testing environments for the refractory metals have been limited primarily to the unalloyed metals and a few alloys of columbium and molybdenum. Most of this work has relied on compositional changes as a means of assesing the effects of various environments on these materials. It has been shown that all of these materials are subject to contamination or purification in various test environments. The residual gases H2, CO(or N2), and H20, constitute the major sources of contamination when testing columbium and tantalum materials in vacua. Under the same conditions, molybdenum and molybdenum alloys containing carbon and reactive-metal additions are subject to serious decarburization. Nonreactive gaseous atmospheres also cause serious changes in material chemistry, since small quantities of noxious gases are contained in the atmosphere. Several promising methods of circumventing material chemistry changes during various longtime, high-temperature exposures are being used and/or evaluated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Effects of Radiation on Materials: Fourteenth International Symposium was presented at Andover, MA, June 1988. The symposium was sponsored by ASTM Committee E-10 on Nuclear Technology and Applications. The papers from the first three days of the symposium appear in the two volumes of this publication. Volume I encompasses radiation damage- induced microstructures; point defect, solute, and gas atom effects; atomic-level measurement techniques; and applications of theory. Volume II includes mechanical behavior, all papers dealing with pressure-vessel steels, breeder reactor components, dosimetry, and nuclear fuels. The fourth day of the symposium was devoted to the single topic of reduced-activation materials (see TK9204). The two volumes are separately sold at $127 and $128 respectively; each is independently indexed. Annotation copyrighted by Book News, Inc., Portland, OR.
Download or read book Structural Materials for Generation IV Nuclear Reactors written by Pascal Yvon and published by Woodhead Publishing. This book was released on 2016-08-27 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operating at a high level of fuel efficiency, safety, proliferation-resistance, sustainability and cost, generation IV nuclear reactors promise enhanced features to an energy resource which is already seen as an outstanding source of reliable base load power. The performance and reliability of materials when subjected to the higher neutron doses and extremely corrosive higher temperature environments that will be found in generation IV nuclear reactors are essential areas of study, as key considerations for the successful development of generation IV reactors are suitable structural materials for both in-core and out-of-core applications. Structural Materials for Generation IV Nuclear Reactors explores the current state-of-the art in these areas. Part One reviews the materials, requirements and challenges in generation IV systems. Part Two presents the core materials with chapters on irradiation resistant austenitic steels, ODS/FM steels and refractory metals amongst others. Part Three looks at out-of-core materials. Structural Materials for Generation IV Nuclear Reactors is an essential reference text for professional scientists, engineers and postgraduate researchers involved in the development of generation IV nuclear reactors. Introduces the higher neutron doses and extremely corrosive higher temperature environments that will be found in generation IV nuclear reactors and implications for structural materials Contains chapters on the key core and out-of-core materials, from steels to advanced micro-laminates Written by an expert in that particular area

Provides a critical and comprehensive review of the state-of-the-art experimental knowledge base of reactor materials, for applications ranging from engineering safety and lifetime assessments to supporting the development of advanced computational models.
Download or read book MeV Proton Irradiation Damage in Tantalum written by Tal Zaharoni and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Refractory metals, such as tantalum and tungsten, are used in nuclear facilities all overthe world as radiation facing components in a variety of applications. In this research,polycrystalline, high-purity tantalum samples were irradiated at the Soreq Applied Research Accelerator Facility by high flux 2.2 MeV proton beam. Ten samples were irradiated and characterized by several methods including optical interferometry, nanoindentation and ToF-SIMS to characterize the radiation damage and determine the change in mechanical properties. The penetration depth of 2.2 MeV protons in tantalumwas measured by several independent tests and agreed with SRIM simulations. Nohydrogen blisters were observed after irradiation to a fluence of up to 1020 P/cm2, morethan three orders of magnitude higher than the blistering critical fluence in tungsten,making tantalum a promising irradiation facing material. -- Abstract.
